Acmena plant named &#39;VICLOW&#39;

ABSTRACT

A new and distinct  Acmena  cultivar named ‘VICLOW’ is disclosed, characterized by short, compact bushy plants. Plants have attractive new growth and foliage colored near greyed-orange. The new variety is a  Acmena  normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Acmena smithii.

Variety denomination: ‘VICLOW’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Acmena, hereinafter referred to by the cultivar name ‘VICLOW’. This new Acmena was developed through a breeding program in New South Wales, Australia. ‘VICLOW’ was selected from a population of seedlings grown from seed resulting from the open pollination of a group of unnamed, unpatented Acmena smithii plants. The open pollination resulting in the new variety was conducted during 2005. Selection of the new variety was made during 1997.

The first asexual propagation of ‘VICLOW’ was carried out during 2000 by softwood cuttings at a commercial nursery in New South Wales, Australia. ‘VICLOW’ has been found to retain its distinctive characteristics through successive asexual propagations. Multiple generations have been propagated, with the new variety characteristics reproduced true to type.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under standard horticultural practices at New South Wales, Australia:

-   -   1. Short plants     -   2. Compact, bushy plants.     -   3. New growth leaf color near Greyed-Orange 166A.

COMPARISON WITH THE PARENT VARIETIES

‘VICLOW’ is distinguished from its female parent in the following:

-   -   1. The new variety produces greyed-orange new growth, whereas         new growth of the parent variety is yellow-green.     -   2. Mature height of the new variety is significantly shorter         than that of the seed parent.

COMMERCIAL COMPARISON

‘VICLOW’ is similar to the commercial variety Acmena ‘Allyn Magic’, unpatented, in most horticultural characteristics. ‘VICLOW’ however differs in the following:

-   -   1. Plants of the new variety produce a broad leaf, with an         average diameter of 39 mm, average leaf diameter of this         comparator is 14 mm.     -   2. Leaf color of new growth of the new variety is greyed-orange         166A, of the comparator Greyed-Orange 177A.

DESCRIPTION OF THE PHOTOGRAPHS

This new Acmena is illustrated by the accompanying photographs which show the plant's form, foliage and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. Plants were grown in New South Wales, Australia.

DESCRIPTION OF THE NEW CULTIVAR

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2015 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SMNBDO’ plants grown outdoors, in Kulnura, Australia. The growing temperature ranged from about 10° C. to 38° C. during the day and from 5° C. to 28° C. during the night. General light conditions are natural sunlight. Measurements and numerical values represent averages of typical plant types.
